Hong Ye HY-630 is a high-performance condensation-cure Liquid silicone rubber specially formulated for Christmas decoration and holiday ornament mold making. With a Shore A hardness of 30, excellent tear strength (≥28 kN/m), and low shrinkage (<0.3%), this silicone is engineered to capture intricate details in holiday ornaments — from snowflakes and reindeer to Santa figures, nutcrackers, and intricate bauble patterns — while delivering the durability required for high-volume seasonal production runs.
The holiday decoration industry is characterized by seasonal demand spikes, tight production schedules, and a need for consistent quality across thousands of identical pieces. HY-630 addresses these demands with a fast curing profile (3–4 hours demold time at room temperature), a forgiving 100:2–5 mix ratio (Part A : curing agent), and a mold life of 800–1,000 casting cycles. Whether you are producing resin Santa figurines, plaster Christmas ornaments, cement garden holiday decor, or wax candle holders, HY-630 provides the detail fidelity and production reliability that seasonal manufacturers depend on.
Produced by Shenzhen Hong Ye Jie Technology Co., Ltd. — a silicone manufacturer with 25+ years of experience exporting to 138+ countries — HY-630 is backed by ISO 9001, RoHS, and REACH certifications, ensuring consistent quality and regulatory compliance for global buyers.
1. Low Shrinkage for Consistent Ornament Dimensions HY-630 delivers cure shrinkage below 0.3%, ensuring that every ornament cast from the mold maintains consistent size and shape. For holiday decorations that are often displayed in sets or hung in groups, dimensional consistency is critical — uneven ornaments look unprofessional and are difficult to package. HY-630's low shrinkage eliminates the need for pattern scaling adjustments and reduces post-casting trimming.
2. High Tear Strength for Extended Mold Life With a tear strength of ≥28 kN/m and tensile strength of ≥6.0 MPa, HY-630 molds withstand repeated demolding of complex holiday shapes — including antlers, hanging loops, thin icicle details, and undercut ornament designs. Typical mold life reaches 800–1,000 casting cycles, significantly reducing the cost per ornament during peak seasonal production.
3. Fast Curing for Seasonal Production Schedules The holiday season is short — manufacturers often need to produce thousands of pieces in a 6–8 week window. HY-630 demolds in just 3–4 hours at room temperature (25°C), allowing multiple production cycles per day. For even faster turnaround, mild heat (40–50°C) can reduce demold time to 1.5–2 hours without compromising mold quality.
4. Excellent Detail Reproduction Many holiday ornaments feature fine surface details — embossed patterns, glitter texture simulation, facial features on Santa/elf figures, intricate snowflake geometry, and decorative filigree. HY-630's flowable consistency (viscosity 28,000–35,000 cps) penetrates these details during pouring, capturing surface textures down to 0.05 mm. The result is ornaments that match the master pattern with exceptional fidelity.
5. Easy Mix Ratio and User-Friendly Operation HY-630 uses a simple 100:2–5 mix ratio (Part A silicone base : Part B curing agent), adjustable to control cure speed. No specialized equipment is required — a digital scale, mixing container, and brush or pouring cup are sufficient for most operations. This makes HY-630 accessible to both small artisan workshops and large industrial production facilities.
6. Broad Material Compatibility HY-630 is compatible with a wide range of casting materials commonly used in holiday decoration manufacturing:
7. Cost-Effective for High-Volume Seasonal Production Compared with addition-cure (platinum) silicones, HY-630 condensation-cure silicone offers a lower upfront material cost while still delivering 800–1,000 mold cycles. For manufacturers producing large quantities of holiday ornaments where food contact is not required, HY-630 provides an optimal balance of performance and cost-efficiency.

Seasonal Production Environments
Step 1: Prepare the Master Pattern Ensure the master ornament pattern is clean, dry, and free of dust, grease, or release agent residue. For 3D-printed patterns, sand smooth and apply a sealant coat to prevent surface porosity. Apply a thin, even layer of appropriate release agent (wax or PVA) to facilitate demolding.
Step 2: Build the Mold Frame Construct a containment box around the pattern using cardboard, wood, or acrylic, leaving 10–15 mm clearance for the silicone wall. Seal the base with clay or hot melt adhesive to prevent leakage. For two-part molds, build a clay parting wall along the intended split line and insert registration keys.
Step 3: Weigh and Mix Weigh Part A (silicone base) and Part B (curing agent) according to the 100:2–5 ratio. The exact ratio can be adjusted: more curing agent speeds up cure; less extends operation time. Mix thoroughly in one direction for 2–3 minutes, scraping the sides and bottom of the container.
Step 4: Degas (Recommended) For best results, place the mixed silicone in a vacuum chamber at -0.095 MPa for 2–3 minutes until bubbling subsides. This step is especially important for ornaments with fine surface details where even small bubbles would create visible defects.
Step 5: Pour or Brush Pour the degassed silicone slowly from a low height into one corner of the mold frame, allowing it to flow across the pattern naturally. For highly detailed or vertical surfaces, first brush a thin coat onto the pattern surface, then pour the remainder.
Step 6: Cure and Demold Allow the silicone to cure at room temperature (20–25°C) for 3–4 hours. Once fully cured (no tacky surface, firm to the touch), remove the frame and carefully peel the silicone mold from the pattern. For two-part molds, separate the halves along the parting line.
Step 7: Post-Cure and Production Allow the mold to post-cure for an additional 4–6 hours before first production use. This maximizes tear strength and dimensional stability. Before each cast, apply a light release agent for resin or cement casting; for wax and soap, the silicone's natural release properties are usually sufficient.
